To all whom it mayconcem:

Be itknown that. I, EDWARD L. AGKER-s specification, reference being had therein. to

the accompanying drawings.

The invention relates to hinge or pivot construction for. windshieldsand for. similar constructions, and it is the object of their.-

vention, first, to obtain a construction that may be formed by dies from fiat sheet metal blanks; further, to provide .a friction. bearing, which may be adjusted to hold the-shield frolnaccidental movement, while permitting of free adjustment when desired. With these objects in view the inventionicomprises the construction as hereinafter set forth. In the drawings 7 V p Figures 1 and 2 are perspective. views of the cooperating formed sheet metal members; q

Fig. 3 is a cross section in the plane of the pivot; and

Fig. i is a section in a plane at' right;

angles to Fig. 3.

A is the windshield frame which may be a'channel tube of any desired section, but shown as substantially rectangular; B is a portion of the frame or bracket, to which the shield is pivotally attached and which is apertured and provided with conical bearings C and D on opposite sides of the aperture; and E and F are members struck up from sheet metal, each being provided with a conical portion for fitting the conical bearings C and D respectively. The member E has a cu ped portion providing the conical portion 8 and beyond the cup portion are flanges H and H .fashioned'to embrace the tube A and secured thereto in any suitable way. The member F is also cupped, but has its flange bent inward to form the conicalportion I provided with projecting lugs J and J on opposite sides thereof for en gaging apertures K and K in the member E, so as to interlocktherewith to prevent relative rotation. The member E is centrally apertured to receive a clamping bolt L having a head L within the cupped porshank L for engaging an aperture on the same frame so as to prevent rotation; The

member F is centrally apertured at M for the passage of the bolt L, and a clamping nut N is adapted to engage the threaded end of this bolt outside vof the member F to draw said memberand the member E together upon opposite sides of the bracket B. With the construction describechfthe' main elements are formed from sheet metal by die operations, which greatly decreases the cost. of manufacture by avoiding all machining. Furthermore, {the work may be absolutely standardized, so that the parts will be interchangeable. a What I claim asmy invention is j 1. In a hinge or pivot. centerconstruction, apair of cupped sheet metal members providing oppositely-inclined conicalib'ear- 'ings, a central clamping bolt for-connecting said, members, and a lug. projectingf'integrallv from one of said members parallel to the pivotal axis and into interlocking engagement with the other member, for preventing relative, rotation; a v 1 1 V v 2. Inahinge or pivot center construction, the combination with an apertured member having conical annular bearingson opposite si des-;.thereof, of a pair of cupped sheet metal members having conical faces for engagingthe opposite sides of said apertured' member, a central bolt'having a head en gaging the cup of one of said members, and a shank projecting through a central aperture in the other of said members, and

' necting said sheet metal members having a head engaging the recess in one of the cups, and a threaded shank pro ecting through an aperture in the other cup, 'a nut threaded I for engagement with said shank, anda lug projecting from the conical flange of one of said members into engagement with a locking recess in the other member.

4. In a hinge orpivot'center construction,

the combination with an apertured member having bearings on opposite sides thereof, of a pair of cupped sheet metal members, one of said members having a flaring flange and the other a tapering. flange for forming respectively conical bearings engaging the conical bearing in said apertured member and a lug on the tapering flange extending through the aperture in said apertured mem-' ber and interlocking Withthe member having the flaring flange.

5. In a hinge or pivot center construction, the combination with an apertured member having conical bearings on opposite sides thereof, of a pair of cooperatiiw cupped sheet metal members, one of said members being provided With flaring flange and the other With a tapering flange forming conical bearings for respectively engaging the bearings on said apertured member, a bolt having a headengagingthe recess in the cup of the flaring flanged member and passing'through central aperture in the tapering flanged member, a lug on said tapering flange passing through the aperture in said apertured member and interlocking with said flaring flange member,flanges on said flaring flanged member for embracing the member to be attached thereto, and a nut engaging said bolt and bearing against said tapering flanged member.

6. In a hinge or pivot center construction, comprising an apertured member having conical annular bearings on opposite sides thereof, a pair of cupped sheet metal mem- Gopies of this patent may be obtained for five cents each,
